Edge

Where 2 faces meet

Face

The side of the shape

Base

The bottom of the shape

Cone

3D with one vertex and one circular base. Not a polyhedron

Rectangular Prism

Is a 3D shape that has 2 rectangle bases and 4 rectangles faces

Triangular Prism

Is a 3D shape that has 2 triangle bases and 3 triangle bases

Hexagonal Pyramid
